Mainline CIPP Coupling

LMK Technologies is the exclusive distributor of non-shear rubber couplings made specifically to fit the outside diameter of cured in-place pipe in order to connect to direct bury pipe. The exterior of the couplings are shielded with stainless steel to eliminate shifting which could result in offset joints. Stainless steel nuts and bolts offer superior clamping and non-shearing. These clamping mechanisms provide 50-lbs per inch of pipe shear protection where there is a need for resistance to heavy earth loads, shear forces and improved alignment.
